How can I change my WhatsApp phone number?
Note: Make sure to use the specific Change Number steps to migrate your account to your new number. If you simply verify a new number with WhatsApp (you might see a prompt to do this when you put a new SIM card in your phone and open WhatsApp) then your old account data will not migrate over to the new account.
If you are planning on using your old number in the future - for example, if you will temporarily use this new number on vacation - or you simply do not wish to delete your old account number, just delete and reinstall WhatsApp. Deleting the application will not delete the account tied to your previous number. Once reinstalled, you can verify a new phone number.
Note: At this time, Nokia S60 users should use the delete and reinstall steps to change their phone number.
